Abstract

Appropriate surveillance and risk-reducing surgery based on genetic testing may lead to early diagnosis and the prevention of HBOC. In Japan, the current situation regarding genetic testing or appropriate treatment based on genetic testing for family members of patients with BRCA1/2 pathogenic mutations is not clear. The purpose of this study was to investigate genetic testing rates and background characteristics of examinees in Japanese pedigrees with BRCA1/2 mutations. We statistically analyzed records from the Japanese HBOC consortium. Seventy-five of 180 pedigrees (131 people) with BRCA1/2 mutations underwent genetic testing. The examinees were mostly female, and often belonged to pedigrees having a strong family history. Based on these results, it is important to disseminate correct knowledge about HBOC to medical workers and the general public.
